5 Claims. 1

The present invention relates to improvements in a drainage receptor for collecting the waste from the body of a person who has undergone an ileostomy or a colostomy operation and has for an object to provide a device of this kind which is supported by the body of the patient. Another object of the present invention is to provide an improved receptor in which when adhesive means is employed to support it from the body of the patient the drainage receiving bag or container may be removed and a fresh one replaced without disturbing the adhesive means.

A further object of the present invention is to provide an improved device of this character comprising relatively few parts which can be quickly and easily assembled and disassembled for cleaning and the like.

A still further object of the present invention is to provide an improved receptor in which the several parts when in assembled relation set up leakproof joints between the several parts.

The present invention aims to provide an improved drainage receptor which when in position upon the body of the patient will lie substantially flat thereagainst so as not to create a bulky appearance.

The present invention also aims to provide an improved device of this character which will readily accommodate itself to movements of the body of the patient without dislodging the device from the proper position upon the body.

In one of its broad aspects the present invention contemplates an improved drainage receptor, comprising a body engaging plate having a passageway therethrough, a drainage receiving bag I 1 scribed and more particularly pointed out in the Figure 2 is a side elevational view of the improved device with parts broken away;

Figure 3 is an enlarged sectional view taken on the line 33 of Figure 2 and looking in the direction of the arrows; and

Figure 4 is an exploded view of the various parts comprising the improved, receptor.

Referring more particularly to the drawings, I0 indicates a body engaging member or plate which can be made of plastic, metal, or any other appropriate material and has an inner surface adapted to engage the body of the patient provided with a substantially flat centrally disposed portion II and a peripheral portion H a which slopes outwardly from the flat portion towards the outer edge of the plate ID. The plate I!) has a substantially centrally disposed boss l2 and the plate and the boss have a through passageway l3. The plate H! has an outer substantially flat surface 14 from which the boss l2 projects outwardly at substantially right angles thereto.

One member of a fastening element which can be in the form of a substantially U-shaped member generally indicated at l 5 having spaced apart parallel legs l6 and I! connected by a bridge piece I 8 is attached to the outer surface I4 of the plate I0 near its outer peripheral edge by a rivet or the like IS. The rivet l9 extends through the leg l6 of the member l5 and through the plate I0 and has its head countersunk in the portion Ha of the inner surface of the plate Ill. The member I5 is attached to the plate l0 so that its open end is facing the boss [2.

A similar member [5 is attached in a similar manner to the plate [0 at a point diametrically opposite to the first member I 5. The members l5 can be made of any suitable material and can be molded integral with the plate II].

A bag or container for collecting waste or drainage emanating'from the incision madein the body of the patient is indicated at 20 and can be made of plastic or any other suitable leakproof substance which is disposable after use. The bag 20 has'a neck 2|, the open mouth portion of which is folded around a fiat band 22 of substantially rectangular cross-sectional shape as indicated at 2la, 2lb, 2lc and 21a. The band 22 can be cut out of corrugated paper or other suitable material that is disposable after use.

A bag supporting disk 23 of plastic or other appropriate material has a substantially centrally disposed through opening 24 for receiving the boss l2 therethrough. The disk 23 has an inner flat face 25 which is adapted to snugly engage the outersurface M of the plate "I when the parts are in assembled relation as shown in Figure 3. A socket or recess 26 is formed in the inner portion of the disk 23 and communicates at one side with the opening 24 of the disk and its inner end opens through the face 25 of the disk 23 so that the socket has a bottom wall 21 and a side wall 29.

The disk 23 has a pair of U-shaped fastening members 29 attached thereto at diametrically opposite points which are similar to the members I5. Each member 29 has a pair of parallel spaced apart legs 30 and 3| connected by a bridge'piece 32. A rivet 33 extends through the disk 23 and the leg 30 of each member 29.

The boss I2 adjacent its outer free end is provided with an annular groove 34 for receiving a snap ring 35 which can be in the form of a coiled spring. The inside diameter of the spring 35 when in its normal contracted position is less than the outside diameter of the grooved portion of the boss l2.

The bag 20 can be made of any desired size or shape to fit the individual needs of the patient. It is also to be understood that the dimensions of the other parts of the device may be varied to meet the requirements of different individuals. The plate Ill and the disk 23 may be made in various shapes, such as oblong, square or oval. lln the use of the device, the surgeon. or other operator will place the spring 35 around the neck 2| of the bag 2! and thread the neck 2| through the opening 24 in the disk 23. The band 22. will then be inserted into the open mouth of the bag 20 and the mouth portion of the bag will be folded around the band 22. The band'22 and the folded portion of the mouth of the bag will be inserted into the socket 26 in the disk 23 which will then be slipped over the boss [2 until the face 25 of the disk is brought into contact with the outer surface I 4 of the plate ID. The spring 35 will then be snapped into the groove 34 of the boss l2. The location and size of the groove 34, the thickness of the disk 23 and the outside diameter of the spring 35 are such that the spring 35 when located in the groove will urge the disk into snug engagement with the surface M of the plate Ill. The spring 35 will also serve to clamp a part of the neck 2| of the bag into tight engagement with the wall of the groove 34 to set up a liquid tight seal at this point against passage of any fluid passing from the incision of the patient through the passageway |3 of the plate l and boss |2.

Further fluid tight seals are set up between the folded portions 2 la and 2 lb of the neck 2| of the bag and the bottom 21 and the side wall 28 of the socket 26, respectively, and between the folded portions 2|c and 2|d of the neck 2| and the outer surface I 4 of the plate I 0 and the outer wall of the boss l2, respectively.

When the device has been assembled as described above, the operator will then place a belt 36 about the waist of the patient indicated at 31. The belt 36 is provided at each of its free ends with an eyelet 38 which receive the leg 3| of the respective fastening members 29 on the disk 23 whereby the belt 36 will hold the assembled device in proper position over the incision so that the passageway |3 will be in communication with the incision to conduct any drainage therefrom and into the bag 20.

It will be noted that the disk 23 is positioned upon the boss l2 of the plate l8 so that the fastening members l and 29 are angularly spaced apart approximately ninety degrees. The fastening members are so disposed to prevent the fastening elements l5 from interfering with the connection between the eyelets 38 and the fastening elements 29. If necessary or desired, additional supporting means may be provided for the device in the form of double faced adhesive tape 39 or any other suitable adhesive which does not after removal require the cleaning of the body of the patient. The adhesive tape 39 is attached to the plate I!) and the body of the patient. l

' When the operator wishes to remove the bag 20, this can be done without disturbing the plate I0 andthe adhesive 39 by disconnecting the eyelets 38 from the fastening members 29 and removing the spring 35 from the groove 34 of the boss |2. The disk 23 and the bag 20 can then be removed and a fresh bag 20 substituted. While the bag is being changed the eyelets 38 of the belt 36 can be engaged with the legs I! of the fastening members I5 of the plate I0. I

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
